Answer: 10 units.
Step-by-step explanation:
The equation of the circle in Center-radius form is:

Where the center is (h,k) and "r" is the radius.
The equation of the circle given is:

You can observe that is written in Center-radius form.
Then, you can identify that:

Knowing this, you need to solve for "r" to find the lenght of the radius.
This is:

Therefore, the lenght of the radius is 10 units.
Answer:350
Step-by-step explanation:
Just take away 9,550 - 9,200 = 350
Answer:
Proportion of female older Than 60 in country A is not more than the proportion of female older Than 60 in country B.
Step-by-step explanation:
From. The plot given :
We could approximate the proportion of females older than 60 as follows _
COUNTRY A :
60 - 69 = 0.105
70 - 79 = 0.065
80 - 89 = 0.038
90+ = 0.01
Total = About 0.218
COUNTRY B :
60 - 69 = 0.14
70 - 79 = 0.11
80 - 89 = 0.07
90+ = 0.02
Total = About 0.34
From the estimated proportion, the proportion of females on country B is more than the proportion in country A.
Answer:
28 , 28, -14
Step-by-step explanation:
x2+6x+8=0
4(2)+6(2)+8=0
8+12+8=0
28=0
x2+6x+8=0
-4(2)+6(2)+8=0
8+12+8=0
28=0
x2+6x+8=0
-8(2)+6(-1)+8=0
-16-6+8
-14=0
Answer:
C, x^3+x^2−7x−15
Step-by-step explanation:
=(x+−3)(x^2+4x+5)
=(x)(x^2)+(x)(4x)+(x)(5)+(−3)(x^2)+(−3)(4x)+(−3)(5)
=x^3+4x^2+5x−3x^2−12x−15
=x^3+x^2−7x−15
